ISLA216P25

16-Bit, 250MSPS ADC

OVERVIEW

The ISLA216P is a family of low power, high performance 16-bit analog-to-digital converters. Designed with Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process, the family supports sampling rates of up to 250MSPS. The ISLA216P is part of a pin-compatible portfolio of 12 to 16-bit A/Ds with maximum sample rates ranging from 130MSPS to 500MSPS.

A serial peripheral interface (SPI) port allows for extensive configurability, as well as fine control of various parameters such as gain and offset.

Digital output data is presented in selectable LVDS or CMOS formats. The ISLA216P is available in a 72-contact QFN package with an exposed paddle. Operating from a 1.8V supply, performance is specified over the full industrial temperature range (-40°C to +85°C).
